PROBLEM TO BE SOLVED: To provide a light-emitting device having a plurality of light-emitting parts, in which variation in the ratio of capacitance of the light-emitting part to the capacitance of a wiring part among a plurality of light-emitting parts is suppressed, an organic layer is sufficiently sealed, and manufacturing cost of the light-emitting device is prevented from increasing.SOLUTION: A light-emitting part 140 includes: a first electrode; an organic layer; and a second electrode 130. The second electrode 130 is a part of a conductive layer. The wiring 200 is connected to the first electrode 110, and an insulation layer 150 is located on the wiring 200. A coating film contains an inorganic material and the light-emitting part 140 and the wiring 200 are overlapped with each other. A second region 132 of the conductive layer is located on the wiring 200. At least a part of the second region 132 is separated from the second electrode 130. Then, a gap 134 between the second electrode 130 and the second region 132 is covered with the coating film.SELECTED DRAWING: Figure 1 【課題】複数の発光部を有する発光装置において、発光部の容量と配線部の容量の比が複数の発光部の間でばらつくことを抑制し、有機層を十分に封止し、かつ発光装置の製造コストが増加しないようにする。【解決手段】発光部１４０は、第１電極、有機層、及び第２電極１３０を含んでいる。第２電極１３０は導電層の一部である。配線２００は第１電極１１０に接続しており、絶縁層１５０は配線２００の上に位置している。被覆膜は無機材料を含んでおり、発光部１４０及び配線２００と重なっている。配線２００の上には導電層の第２領域１３２が位置している。第２領域１３２の少なくとも一部は、第２電極１３０と分離している。そして、第２電極１３０と第２領域１３２の隙間１３４は、被覆膜で覆われている。【選択図】図１
